Splitter/duplicators are versatile with software setup, feature several options

Acromag's new SP330 series of isolated signal splitter/duplicators are designed to accommodate a variety of applications. These four-wire DC-powered models are software-configurable for precise conditioning of current, voltage or temperature input signals. The SP330 splitters provide two isolated outputs, proportional to a signal input, with a choice of process control signal formats: 0-20mA, 4-20mA, 0-5V, 0-10V, ±5V or ±10V. A standard USB port connects the splitter to a PC or Android device with Acromag’s free software for easy selection and scaling of I/O ranges. Power sources from 6 to 32V DC are supported and can connect at the terminals to a power bus along the DIN rail, or at both locations for redundancy. The rugged design features removable terminal blocks to simplify wiring and a metal spring-loaded DIN rail clip for easy insertion or removal in panels. To ensure reliable performance, units are highly immune to electrical noise, protected from surges, and operate from -40 to 75°C. Hazardous location approvals are pending for UL Class 1 Div 2, ATEX Zone 2 and IECex standards. The units are adjustable to support ±20mA or 0-20mA DC inputs and 0-20A AC signals with a toroid sensor. Voltage models convert unipolar or bipolar signals from ±1V to ±150V DC with multiple selectable ranges. Thermocouple units accept eight different sensor types (J, K, T, R, S, E, B and N), as well as ±100mV inputs. All models support a choice of six output ranges including 0/4-20mA current and unipolar or bipolar voltage ranges for 5V and 10V control signals.
